Copy the city-by-city times, share a meeting link, or download a calendar event. The event records an exact UTC start and end. Shared links include the selected cities and meeting details, so only include information you intend to share.
The planner validates Gregorian dates, including leap years. A skipped clock time produces a clear error. When a clock time happens twice, choose its first or second occurrence using the displayed UTC offset. Meeting duration is elapsed time, even across a clock change.
Search cities around the world, or enter an IANA time zone such as Asia/Kathmandu or UTC. Your city list stays on this device. Download an .ics event or open a Google Calendar or Outlook draft to review before inviting colleagues.
City data adapted from GeoNames, under CC BY 4.0. Time conversions use your browser’s IANA time zone data. Working hours are fixed at 09:00-17:00, using regional working days for city search results and Monday-Friday for time zones without a country. Public holidays are not included. This tool compares typical working hours and does not read anyone’s calendar availability.
